Incoming message EXO can receive messages from monitoring personnel via Blackline Live. Messages are available in your device's Message inbox. See the Text Messages section for more information on messages. The incoming message notification is activated as soon as your device receives a message. | |
|
Two-way voice call If EXO has the two-way voice call feature enabled and is in cellular coverage, it can receive two-way voice calls from monitoring personnel, such as during a response to a high-urgency notification. You cannot initiate or end voice calls from EXO. Voice calls are automatically answered by EXO. See the Two-way Voice Calls section for more information on two-way voice calls. | |
|
Errors (hardware, cartridge, sensor, firmware) The error notification is activated when EXO experiences an error (e.g., your gas sensor stops working). If the gas expansion module is installed in your device, the error notification is also activated when the module experiences an error (e.g. a sensor in the module stops working). Note:
Following an error notification, Blackline recommends that you power off and restart your device. If the error persists, try updating the firmware (see the Over-The-Air Firmware Updates section). If the error does not clear, contact Blackline Technical Support. | |
|
Low threshold The low gas threshold is configurable in Blackline Live. The low gas notification is activated when gas levels reach the configured threshold for your device. Note:
An EXO with an O2 sensor notifies you in both oxygen-deficient and oxygen-enriched atmospheres. An oxygen-deficient atmosphere poses a risk of insufficient oxygen for breathing. An oxygen-enriched atmosphere presents an increased risk of explosion. Note:
You can choose to mute the sound portion of a low-gas notification, but the lights remain active. Persistent lights and recurring sounds are there to encourage you to leave, and to help emergency responders locate you if you lose consciousness or cannot remove yourself from the area. After acknowledging a low-gas notification, move to an area where gas is not present. If you do not leave the area and gas levels remain above the low threshold, the low gas notification reactivates after two minutes. | |
|
Sensor under limit The sensor under limit (UL) notification is activated when your device detects a UL event. Note:
Following a UL notification, no peak is logged because the UL event type is closely related to a device or sensor error. To resolve the UL event, Blackline Safety recommends that you calibrate your device. For more information on calibration, refer to the Calibration section. | |
|
Pump blocked The pump blocked notification is activated when your pump inlet is blocked. | |
|
Tumble alarm (Optional) When tumble alarm is enabled, EXO triggers a low-urgency notification if it is knocked over. In addition to lights and sounds, you can view the event in the device history and, if a notification profile is configured, a message is sent to identified contacts. | |
|
AlertLink AlertLink notifications let you know that another G7c, G7x, EXO, or EXO 8 Gamma device within the configured proximity radius is experiencing a high urgency event. AlertLink notifications trigger a unique light and sound pattern. Note:
AlertLink is only available for self-monitored or Blackline-monitored organizations. Your EXO receives a message at the time of the triggering event, which includes the alert type, the assigned user of the origin device, the origin device type, other device information, and gas type when applicable. When the AlertLink notification is activated, proceed based on your company’s safety protocol. You can configure the notification to persist for a maximum of 90 minutes until it is manually acknowledged on the device or to clear automatically after pre-set period of time (15-minute default). The notification can also be cleared remotely by monitoring personnel in Blackline Live. AlertLink functionality and the proximity radius can be configured in Blackline Live. You can also exclude EXO devices from receiving AlertLink notifications in Blackline Live. For more information, see the Blackline Live Technical User Manual. | |
|
Low gamma If your EXO device has a gamma sensor installed, the low threshold notification is activated when gamma levels reach the configured threshold for your device. The low gamma threshold is configurable in Blackline Live. Note:
You can choose to mute the sound portion of a low gamma notification, but the lights remain active. Persistent lights and recurring sounds are there to encourage you to leave, and to help emergency responders locate you if you lose consciousness or cannot remove yourself from the area. After acknowledging a low threshold notification, move to an area where gamma radiation is not present. If you do not leave the area and gamma levels remain above the low threshold, the low threshold notification reactivates after two minutes. | |
